As the title States It a 13 V6. Never had an issue with car till I went to have new rubber put on. Had a bad TPMS so had that replaced also. They took it off the rack and brought it around front. Paid and went out to leave and car just clicked! They jumped me off and I went on my way puzzled but figured they left lights on or something. Went home and parked it and same thing, just clicked. That was on a Sunday. Charged battery up fully and seemed to start fine. Ran a week with no trouble. Got in to leave work yesterday and again...click, click, click. Jumped it off and went 25 miles to AutoZone close to home. Had them check everything out. Said battery and charging system was fine but battery needs charge? Have checked for vampire draws on battery and can find nothing out of spec. No mods to car everything stock. What the hell? Any help would be appreciated. Thanks in advance. Been twisting wrenches and auto electric diagnosing for 25 years and this has me scratching my head.
